Solution

1. Preparation

Gather necessary tools: screwdriver set, multimeter, OBD-II scanner, and a new fuse (if applicable).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Check the fuse related to the instrument cluster (refer to the owner's manual for the specific fuse location).
If the fuse is blown, replace it with a new one of the same amperage.

3. Check Battery and Connections

Use a multimeter to check the battery voltage. It should read between 12.4V and 12.7V for a healthy battery.
Inspect battery terminals for corrosion or loose connections; clean and tighten as necessary.

4. Inspect Wiring and Connectors

Remove the dashboard cover to access the wiring harness and connectors.
Check for frayed wires, corrosion, or loose connections.
Secure any loose connectors and repair any damaged wiring.

5. Remove Instrument Cluster

Unscrew and carefully detach the instrument cluster from the dashboard.
Inspect the back of the cluster for any damage, particularly the circuit board and solder joints.
If damaged, consider repairing or replacing the instrument cluster.

6. Reassemble and Test

Reinstall the instrument cluster and dashboard cover.
Reconnect the negative battery terminal.
Start the vehicle to check if the dashboard display is functioning.
